H EATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 3353120, dated February 2, 1886.

Application filed April 18, 1885. Serial No. 162,633.

To all whom it may concern.-

Be it known that I, GEORGE BENNS, of Chicago, in the-county of Cook and State of Illinois, have invented certain new and useful Improvements in Heating-Stoves, of which the following is a specification.

This invention has reference to certain improvements in heating-stoves.

In the accompanying drawings, Figure 1 represents a side elevation of my improved heating-stove; Fig. 2, a vertical central section. Fig. 3 is a plan of the same; and Fig. 4 is a horizontal section on the line :0 m, Fig. 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, Arepresent-s the fire-pot of my improved heating-stove, which fire-pot is made of six, eight, or more sides and cast in one piece. The individual sides of the fire-pot A are provided at their inside with diamond-shaped projections a a, that extend from the ends toward the center of the panels, so that the apex of the projections is This has the advantage that the sides of the fire-pot are not liable to warp, bulge, or crack at the points most exposed to heat of the fire. The fire-pot A is supported on the grooved rim d of a basket, B, which rim is again supported on the inner edge of a ringshaped bottom, D, that rests on the upper edge of the wall of the ashpit E. The grooves of the rim d of the basket are made somewhat larger than the base of the fire-pot, so as to provide for the expansion of the same. The basket B is provided with slotted openings, by which air is admitted to the fuel, and with a horizontally-movable grate, G, that is centrally pivoted to a diametrical supporting-piece, I), hung to the basket B, and oscillated thereon by a shaker-rod, b, which passes through the wall of the ash-pit to the outside, as shown in Fig. 4. The ring-shaped bottom D is attached by a downwardly extending flange, e, to the ash-pit E. The exterior part of the bottomD supports a cylindrical jacket, F, that is concentric to the fire-pot, and attached to an upwardly-extending flange, f, of the bottom D. An annular space is formed between the firepot A and the jacket F, which space is closed at the upper part by a fixed perforated ring, F, that supports the (No model.)

upper end of the jacket F. That portion of the bottom 1) outside of the ash-pit wall is perforated, so that the air is drawn in through the openings of the bottom D into the space he tween the fire-pot A and jacket F, heated in its passage through said space, and emitted through the perforations of the top ring, F,

as shown by the arrows in Fig. 2. A perforated slide-ring, f, the openings of which register with the openings of the bottom D, is adjusted by an exterior handle, f so as to open or close the openings of the bottom D and establish or interrupt the passage of air through the annular space around the firepot. 6 The ash-pit is provided at the front part with hinged doors having registers for admitting the proper supply of air to the grate. The upper part of the fire-pot is closed by a domeshaped top, G, which is provided with a sup- 7o ply-opening, g, and a sliding floor, G, that is guided by a ringshaped collar, g, on the upper part of the top G. A magazine, M, at the interior of the fire-pot is provided with a lid,

m, which is opened when the fuel is to be supplied, the magazine being supported by lugs at the upper part of the fire-pot. The base of the stove below the ash-pit may be utilized in the usual manner as a base-flue in connection with a return-flue, in which case connection with the chimney is made by a smoke-pipe at the back of the stove, which pipe is not shown in the drawings.

The advantages of my improved heatingstove are that the same can be used without fire-brick linings until the fire-pot is entirely burned out, after which the same can be replaced at small expense. The air in the room is quickly heated by the circulation of the air through the jacket and by the direct contact 0 of the air with the heated ash-pit and exterior surfaces of the stove.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a heating-stove, the combination of 5 an ash-pit, a ring-shaped bottom resting upon the wall thereof, a fire-pot above said ringshaped bottom, abasket at the lower end thereof, and a grate below said basket, said fire-pot, basket, and grate being supported by said ringshaped bottom, substantially as described.

2. In a heating-stove, the combination of the wall thereof and provided with openings outside said wall, a fire-pot above said ringshaped'bottom, abasket at the lower end there- I 5 of, a grate below said basket, said fire-pot,

basket, and grate being supported by said ringshaped bottom, a jacket surrounding said firepot and supported by said ring-shaped bottom,

and a perforated top ring connecting the upper 20 end of said jacket with the fire-pot, substantially as described.

4. In aheating-stove, the combination of an ash-pit, a ring'shaped bottom resting upon the wall thereof and provided with openings outside said wall, afire-pot above said ring-shaped 2 5 bottom, a basket at the lower end thereof, a grate below said basket, said fire-pot, basket, and grate being supported by said ring-shaped bottom, a jacket surrounding said fire-pot and supported by said ring-shaped bottom, a per- 0 forated top ring connecting the upper end of I said jacket with the fire-pot, a ring resting upon said ring-shaped bottom and provided with openings corresponding with the openings therein, and means for shifting said ring 3 5 to open or close said openings, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

GEORGE BENNS.
